The pictures show the Small hold printed in a carbon/nylon filament but any filament can be used. It is best to lightly sand down the part after printing to remove the shine and provide a little more grip. These holds will work best on overhanging walls - anywhere from 5 to 50 degrees.

These have been designed to take Countersunk M10 bolts and 5mm wood screws.

If you print in PLA please leave 72 hours between the end of printing and first use to allow the print to relax and attain its optimal strength.
